GPT and hemophagocytic syndrome: Taking the current internationally recognized therapeutic evaluation indexes of HLH as the main breakthrough point, including sCD25, serum ferritin, triglycerides, alanine aminotransferase (ALT), blood cells, phagocytic phenomena, and consciousness, we analyzed the traditional laboratory parameters such as serum ferritin, triglycerides, alanine aminotransferase (ALT), and blood cells and investigated their relationship to induction response and their predictive value in HLH patients.
